1. Compare the battery capacity.
Ordinary cadmium nickel battery is 500mah or 600mah, and hydrogen nickel battery is only 800-900mah; The capacity of lithium-ion mobile phone batteries is generally between 1300-1400mah, so the application time of energy storage lithium battery manufacturers after fully charged is about 1.5 times that of hydrogen nickel battery and about 3.0 times that of cadmium nickel battery. If you find that the working hours of the lithium-ion mobile phone battery pack you purchased are not as long as those advertised or the rules in the manual, it may be a fake.
2. Look at the plastic surface and plastic material.
The anti-wear surface of genuine battery is uniform, made of PC material, without embrittlement; The fake battery has no anti-wear surface or is too rough. It is made of recycled material, which is easy to crack.
3. All genuine mobile phone batteries should be uniform in appearance, without redundant burrs, and the outer surface has a certain roughness and feel warm; The inner surface feels smooth, and fine longitudinal scratches can be seen under the light.
The width of the battery electrode is the same as that of the mobile phone battery. The corresponding positions below the battery electrode are marked with [+] and [-]. The isolation material of the battery charging electrode is the same as that of the shell, but not integrated.
4. For the original battery, its surface color and texture are clear, uniform, clean and free of obvious scratches and damage; The battery mark shall be printed with battery model, type, rated capacity, standard voltage, positive and negative pole mark and manufacturer name.
The handle shall be smooth without obstruction, with appropriate tightness, good coordination with the hand and reliable latch; The hardware sheet shall be free of obvious scratch, blackening and greening. Assuming that the mobile phone battery we purchased does not match the above phenomenon, we can preliminarily conclude that it is a fake.
5. At present, many mobile phone consumer manufacturers also start from their own point of view to improve the counterfeiting difficulty of mobile phones and their accessories through efforts to improve the process level, so as to further curb the phenomenon of a large number of fake parallel goods.
Ordinary and normal mobile phone products and their accessories must be different in appearance. Therefore, we assume that when we install the bought mobile phone battery, we should carefully compare the fuselage with the battery bottom shell? Color, if the color is different from light and dark, it is the original battery. Otherwise, if the battery itself is dull, it may be a fake battery.
6. Observe the abnormal condition of charging.
In general, the genuine mobile phone battery shall have an overcurrent maintainer inside. In case of excessive current caused by external short circuit, the circuit will be automatically cut off to avoid burning or damaging the mobile phone; The lithium-ion battery also has an overcurrent maintenance line. When non-standard electrical appliances are used and the AC current is too large, it will automatically cut off the power supply, resulting in failure to charge. Under normal conditions, the battery can automatically return to the on state. Suppose that during charging, we find that the battery is seriously heated or smoked, resulting in explosion, indicating that the battery must be fake.
7. Look at the anti-counterfeiting signs carefully
For example, hiding the oblique printing of Nokia under the sticker is one of the tricks. Clear and flawless is the original product; Fading is a fake product.
If you look closely, you may also find the name of the manufacturer. For example, the anti-counterfeiting trademark of Motorola battery is diamond shaped, and it can flash with plane effect from any angle. If Motorola, original and printing are clear, it is genuine. On the contrary, once the color is dim, the plane sense is lack, and the words are fuzzy, it may be a fake.
8. Measure the charging voltage of the battery block.
Assuming that nickel cadmium and nickel hydrogen battery blocks are used as lithium-ion mobile phone battery blocks, they must be composed of five single batteries. The charging voltage of a single battery generally does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75v. When the total charging voltage of the battery block is lower than 8.0V, it may be nickel cadmium and nickel hydrogen batteries.
9. Use special tools.
In the face of more and more types of mobile phone batteries in the market, and the technology of impersonation is becoming more and more sophisticated, some large companies are also improving anti-counterfeiting technology from time to time. For example, the new Nokia mobile phone battery has suspended special treatment on the logo and needs to be identified with a special prism, which only needs Nokia. Therefore, with the progress of anti-counterfeiting technology, it is difficult for us to identify the true and false from the appearance.
